Another'and more" specific object of the invenj tiorristo provide a: brooder heater" having a simple compact type of automatic control-unit which may be easily andquickl'y installed and nernoved in its entirety.

A further --obj"ect or the-invention is' toprovide a breeder having a heater ofj the wood-burning type'which is easy to fire and keepisupplied with fuel and which is under automatic control;-

Referring to the drawing in detail, the brooder is heated by a wood burningstove generally indicated at In, the stove preferably being of cylindrical or drumshape and made of sheet metal should be capable of low air downwardly into the stove from said draft op n ng.-

Connected to he nt 051 .1 3 doors n rm q bracket" 21 which projects outwardly and at its tte nd i ooped jor'tu ned in lyy nn nat e in ve s y" be t f ee end por ion 24 n d n t arm s a l ver uidi g a d" supporting member 22- which projects downwardy nci e ves to s port a d uid a er 3, he

latter being pivoted'tosaid member 22 by means of pin 2-4 The one end of the lever 23 has con: nected thereto'a link 25which detachably engages ahook 26 connected to thedamper 20; While the opposite of the lever 23 is provided with a weight ET. The lever 23' may be in the form of a -s'heet' metal section bent inchannel shape and the member 2 2 forms a restrictedlongitudinally extending opening in which the lever has rocking chicks; The. lever 23- is provided with a downwardly' projecting portion 3!- adapted to contact -with-centralportionofthe disc 30: r The upper end of the arm 2 I is formed with a toev 210,: which i'sdetachably engaged-"in a 1ug'32 on the outer-face of the door. When the end or with' front and rear end plates II and I2 secured to the opposite ends of the drum. The drum is also provided with legs l3 and a stack or chimney l4.

Mounted in the front end of the stove is a door l5 which is provided with hinge pins l6 detach-- ably engaged in hinge'lugs Hi. The door may be made of metal of suitable thickness and in actual practice it consists of a casting and carries a closurelatch H. The door is formed with a draft opening I8 which on the outer sideof the door is surrounded .by an outwardly extending wall l9having an upwardly inclined or beveled contour, and mounted on this wall is a damper door 20 which is hinged at its upper end to'said wall. I I

The inner side of the door is provided with a shield l8 overlying the draft opening 18 with its 34, 35 and 3B. The side hood. sections 33 and 34' toe of the arm is inserted in this lugand the arm released, it will hang in proper operating position together with the entire control assembly carried thereby.

Removably. mounted on the heater or stove l 0 is a hover or hood consisting of sheet metal sections, preferably four in number, and indicated at 33,

' are provided with bolting flanges 31 and 31' at their upper edges which at an intermediate point are oppositely recessed to fit-around the stack or chimney I 4. The rear section 35 is detachably connected at its opposite side edges by. bolts 38 to the adjacent edges of the sections 33 and 34; while the front section 36 is hinged as at 39 to a gusset plate 40'which spans the converging upper front edges of the side sections 33 and 34 and is connected to said latter edges; Thus,.the front section may be conveniently raised as in Fig. 2 to gain access to the door I5 of the stove or the control unit mounted on the door.

The side sections 33 and 34 rest on brackets 42 and 43 which in turn rest on the top wall of the stove, to thereby give proper clearance for the hood or hover with respect to the stove.

In operation, whenever it is desired to charge the stove with fuel, the hood section 35 may be swung upwardly and the stove charged through the door 15. The adjusting screw 28 may be set so that the thermostatic disc or discs 3|] will expand and contract within a predetermined temperature range and regulate the damper 20. When the thermostatic discs 30 expand, the weighted end ofv the lever 23 is raised and the opposite end lowered, thereby permitting the damper 20 to move towards closed position and retarding combustion of the fuel. When the said discs contract, the Weighted end of the lever 23 1 is lowered and the damper moved towards 3 open position, thereby increasing the draft in the stove and accelerating combustion of the fuel. The shield 18' on the inner side of the door 15 causes a down draft into and over the fuel in the stove. I

The thermostatic unit may be assembled in its entirety with respect to the supporting arm 2| and the latter then hung onto the door l5 and the link 25 connected to the hook 26. The thermostatic discs are removable and replaceable at any time desired. In certain instances, a purchaser may desire to buy the brooder and stove without the automatic control, in which event the damper 20 may be manually controlled. If at any time repairs are to be made to the control assembly or unit, the arm 2| may be easily and quickly removed, carrying the entire unit therewith. The parts may be manufactured and sold at a relatively low cost, while at the same time the advantages of automatic regulation are optionally available.

The feet of the brackets 42 and 43 extend at a substantially true radius from the peripheral wall of the stove and constitute the sole means of support for the hood or hover, note Fig. 5, thereby reducing heat transfer to a minimum while at the same time providing maximum supporting cylindrical body portion defining a drum, thefront end of said drum having a door hingedly mounted thereon, an arm having a detachable connection with said door and extending outwardly therefrom, a movable damper mounted on said door, a lever pivotally suspended from said arm, one end of said lever being weighted and the opposite end of said lever being connected to said damper, an adjusting screw threaded through the end of said arm and having a supporting member on the upper end thereof, and a thermostatic disc removably disposed on said supporting member and contacting the weighted end of said lever and whereby expansion and contraction of said disc will effect rocking of the lever and regulate the opening and closing movements of said damper.

2. In a brooder, a wood burning stove having a substantially cylindrical body defining a drum, a door for the stove'hingedly mounted in the one end wall of the drum, said door being formed with a draft opening having an outwardly projected wall therearound, a shield on theinner side of said door open at its lower end to cause a down draft of air passing through said opening, a damper hingedly connected to the wall around said opening, an arm detachably connected to the door above said damper, a sheet metal guide member overlying said arm and projecting downwardly therefrom, a lever extending through said guide member and pivoted to the latter, the inner end of said lever being connected to said damper, a Weight mounted on the outer end of said lever, a screw threaded through the inwardl projecting extremity of said arm and having a discsupporting member on the upper end thereof, and a thermostatic disc disposed on said supporting member and contacting the weighted end of said lever and adapted to control the damper through expansion and contraction due to temperature changes within the region of the stove.

3. In a brooder,a stove having a draft opening, a damper for controlling the draft through said opening, an arm detachably connected to the stove and projecting downwardly and outwardly over said damper, a lever pivotally suspended from-said arm, the inner end of said lever being connected to said damper and-the outer end of said lever beingprovided with a weight, a thermostatic disc interposed between the outer end of said arm and the weighted end of said lever, and means for adjusting said disc with respect to said lever.
